Good news!
Crash again at 14:05 w/o OWS running.
I don't use email scanning but I do use sending of emails.
I have 1 schedule running every day at 14.00 that sends email if one of my battery powered devices is below 20%, the crash is usually at 14.05 so I did not suspect that to be the problem.
I did run the schedule manually yesterday => crash a few minutes later and again today => crash.
Then I did remember that my email provider had changed server settings about a week back, changed them in Indigo and it seems to work!!
The bug had to to w/ email SENDING w/ wrong email server settings, not email scanning. Good to know!
Best regards, L
